If you are talking about an interactive shell reading input with ZLE, you
can do it with "zle -U".

If you're in some other way reading from a stream such as standard input,
unget is not possible.  You need a lower-level programming language with
more direct control over things like stdio buffers.  (Unget is not an OS-
level operation, it's implemented in stdio or the equivalent.)
